To my mind "reasonable aperture" rules out anything under 4".
I had an ed80 and was very dissapointed in how little could be seen.
I ended up getting a Vixen R130sf newt on a porta mount.

These are the key benefits I see in this package.
- Yes very lightweight and portable.
- Bigger aperture still in a small lightweight package - Yes it makes a difference.
- Much more comfortable viewing position - can be used standing up and without neck craning.
The downside is that the provided focuser is rubbish, but it can be replaced with an aftermarket one.
